ObjectiveTo explore the value of carbon nanoparticles on surgery for thyroid carcinoma. MethodLiteratures about application of carbon nanoparticles and lymphatic mapping in the thyroid carcinoma were reviewed. ResultsThe carbon nanoparticle was a new lymph tracer with a clear lymphatic mapping and a longer time for dying, which could accurately reflect the status of cervical lymph nodes, trace the sentinel lymph node in the thyroid carcinoma. The parathyroid gland could not be stained black, it was easy to be identified and protected. ConclusionsThe carbon nanoparticle provides an effective help in treatment for thyroid carcinoma. The more extensive and more profound application of lymphatic mapping depends on more clinical study.
